Thanks for the info mate.
I believe that only the first value and wage prices counts.
I believe I find a formula to detect a fast trainer.
Training Factor , for Baxter for example is TR FACTOR VALUE 7.3M / WAGE 85K =85,88 . It's big number so that's why he is fast trainer.
Ok , he is from Academy but if he was in Transfer market and you were thinking to buy or not , this formula could help.
